PETROLEUM-BURNER.

EBPECIFEGATION forming part of Letters Patent No. 316,950, dated May 5, 1885. Application filed August 2, 1884. (No model.)

To all whom it may concern:

Beit known that I, ELIAS B. DE LA MATYR, a citizen of the United States, residing at Ohicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Petroleum-Burners; and I do hereby declare that the following is a full, clear,and exact description of the same,which will enable it to be made and used by others skilled in the art to which it relates, reference being had to the accompanying drawings.

My invention relates to a burner for using petroleum as fuel, and it has for its object to provide such a burner in which the residuum resulting from the imperfect combustion of the oil may be consumed, so that clogging will be avoided. I attain this object by the mechanism illustrated in the accompanying drawings, in which- Figure l is an exterior perspective view of the inclosing-casing containing the burner proper, and connected with an oil-supply tank. Fig. 2 is a perspective view of the casing with its front and end wall removed, in order to show the burner and the interior construction of the casing. Fig. 3 is a vertical section of the apparatus in the plane indicated by the line a; m of Fig. 1. Fig. 4 is a front elevation of an apparatus of I modified construction. Fig. 5 is an end View of the same. Fig. 6 is a vertical section on the line y y, Fig. 4; and Fig. 7 is a detail section illustratinga portion of the construction of the revolving burner. Fig. 8 is a view of the lifter for removing the burner. Fig. 9 is a perspective view of the front part of a stove with myimproved burn er arranged in the fire-box thereof.

Referring now to Figs. 1, 2-, and 3, the letter A indicates a metallic oblong box rectangular in cross-section, and forming the casing in which is suspended the burner proper. The upper portion of the front wall of the casing is ornitted,in order to leave an opening for the escape of the products of combustion. From the top wall of the casing, and from a point about midway its width, a partial partition or flange, a, projects downward with a rearward inclination. This partial partition divides the entire upper portion of the casing longitudinally, and to the rear of said partial partition is a spaceinto which leads oil-pipe 0 from the oil-tank O.

The letter B indicates the burner proper. It comprises two chambers or channels, I) and b, which are open at their opposite ends. Each chamber has an outer vertical side wall,

a, and an inner oblique wall, 0. These oblique ing, so that should the upper portion of one of the chambers be inserted longitudinally behind said partial partition it would hang upon the same in front and rest at the rear against the rear wall of the partition, being thus suspended with its wider open end upward, while the other chamber, being supported by the web a", would stand in front of the partition a with its narrower open end upward. Longitudinally in each of these chambers is arranged a metallic rod, D, of such diameter that it cannot pass through the narrower open end of the chamber, and across the wider end of each chamber are placed oblique cross-bars or wires d, which prevent the rod from escaping from the chamber when its wider portion is turned downward, and these crossbars or wires are also so arranged that when the wider portion of the chamber is downward the rod will lie againstits vertical wall, thus leaving an open space between it and the oblique wall.

The burner B is reversible, so that either one of its chambers may have its wider open end turned upward,while the wider open end of the other is turned downward, and the casing A has a door, A, which may be open to permit the burner to be removed from the casing longitudinally, reversed, and again in sorted in the position clearly shown in Figs. 2

and 3. At the lower portion of the rear casing of the wall are openings 19, to permit air to enter the casing under the burner.

In Fig. 8 the letter R indicates a lifter for removing the burner. It is preferably made of metal, either cast or wrought, and has a handle, 1', and two prongs, r, at a proper distance apart to fit nicely over the edge of the web 0 which connects the oblique walls of the two chambers of the burners. The manner of using the handle is obvious.

The mode of using my invention is as follows: The burner B being inserted in the easing, as shown in Fig. 3, the door of the casing A is closed and the whole inserted in the firebox of a stove or furnace in such manner that the door A of the burner-casing will coincide with the door of the firebox, as shown in Fig. 9. The opening at what I have termed the front of the burner-casing is preferably turned toward the fire-bacl, but it may be turned either way. The oil-tank O is placed in any convenient position above the level of the burner-casing, and may be led into the fire-box through a suitable opening in its wall and connected with the other portion ofthe burner-casing, as shown in Fig. 1, and project in the said casing, as shown in Fig. 3, but does not reach down as far as the burner. The pipe has a cock, 0, to regulate the fiow of the oil, and when this cock is opened the oil flows in that chamber or burner which stands behind the partial partition a, and falling upon the rod D at the bottom of said rod will ooze around it and appear upon its lower surface, where it may be ignited by a match or torch inserted through the doorway of the casing. The air coming in at the openings 19 promotes the combustion of the oil and forms a draft which passes through the outer chamber of the burner and the space between said chamber and the front wall of the casing, escaping at the longitudinal opening at the front upper portion of the casing, and passing through the flues of the stove or furnace; The oil burns mainly on the bottom of the rod D and the lower edges of the walls of its chamher; but, combustion not being complete at these points, a residuum accumulates, and if not removed would in time clog the passage around the rod and obstruct the flow of oil. To complete the combustion it is only necessary to withdraw the burner Bfrom its casing, reverse and replace it so that the chamber, which at first stood in front of the partial partition (1/ with its narrow end upward, will now be suspended behind said partial partition with its wider end upward. Its rod D will fall and loosely close its lower end,while the rod of the other chamber, partially covered with residuum, will rest upon the cross bars or wires (1 of said chamber and against itsouter vertical wall. It will now be seen that the chamber, which at first was the oil channel or chamber, has now become the flame chamber or channel, and the rod falling to the wider opening of the flame-chamber has the residuum completely burned therefrom, which leaves the rod clean. Any residuum will also be consumed which may have collected on the edges of the chamber-walls.

In the modifications of my invention, illus trated in Figs. 4, 5, 6, and 7, the burner is constructed for the reversal of its chambers by giving it a halfirevolution on a longitudinal axis, instead of withdrawing it from the easing and reinserting it in a reversed position. In this modification the casing A is constructed substantially as in the first-described form of the apparatus; but instead of having the rearwardly-inclined partial partition 64 it has a narrow partialpartition, (6, projecting vertically downward. Below this partial partition a is arranged a cylindrical burner, 13', which has a longitudinal diametric partition, f, through its entire length so as to divide the cylinder into two chambers, b and b the outer walls, 0, of which are transversely oblique to the central partition on their inner'surfaces, but are parallel to each other, so that the chambers of each have a wider and a narrower open end, the narrow end of one being in the same direction as the wider end of the other, and so that when the burner is in position, as indicated in the sectional Fig. 6, the wider end of one chamber will be turned upward, as will also the narrow open end of the other. The ends of the chamber are closed by the heads B of the cylinder, which are provided with inwardly projecting flanges t, which serve to prevent the rods D from escaping from the chambers, the same as the crossbars (I prevent said rods from escaping from the chambers of the other form of burner. Through these heads of the cylinder pivotpins (1 project from the end of the central partition, f, and these pivot-pins have hearings in the end walls of the casing A one of said pivot-pins being square at its tip, or otherwise formed to receive a suitable handle by which the cylinder may be turned. The end wall of the casing, which corresponds to the door end of the other form, is provided with a small opening, as shown at a, through which the oil may be ignited, and this opening is normally closed by a swinging door, a, which .may be swung to one side, when required.

The mode of using this modified form of the apparatus is the same as that for the form first described, except that when the chambers are to be reversed the burner is simply given a half-revolution instead of being withdrawn from its casing, turned, and reinserted. The force of the draft and products of combustion, and the burning of the residuum, is the same as in the apparatus first described.

Stoves or other structures in which my improved burner is used are to be managed in all respects as when other fuel than petroleum is used, the heat and other products of combustion passing into the fines and chimney in exactly the same manner.

Having now'fully described my invention and described the operation thereof, I claim 1. The reversible burner having duplicate chambers or channels arranged reversely to each other, and provided with the shifting bottom rods or pieces, substantially as described.

2. The combination, with the casing having than at the other, of the shifting-rods D D, ar-

ranged to change their positions by gravity and toclose the bottoms of said chambers alternately.

4. The combination of the reversible burning bottom rods 'with'the casing having the downwardly-projecting partial partition, the air-inlets, the oil-pipe connection, and the front opening for the escape of products of combustion, substantially as described.
